Hard to judge by region. My American number that I've had a while gets 4-5 spam calls a day and about five texts a week, and it's all trending up, despite whatever the phone companies say they're doing.

The newest one seems to be group FaceTime calls (to about 20 numbers) that hang up after a couple seconds. Not sure what the angle is there; makes me wonder if there's an associated iPhone 0-day. Or maybe just probing phone type.
